Fuck that shit; its time to tell life to go stick it up its ass. Don't take shit from life. If like gets you down, kick it in the balls and strangle it once it hits the floor, then stand back up and dust yourself off.
Most people think that you just "recover" from shit like that. You don't just "recover" magically like some angel came down and gave you a high-five. Recovery is a job. You have to get your head straight, your body straight, and your friends and family straight. Usually, it works best if you do all three at the same time. Go swimming, have a pool party, and do some homework. Then, get pictures of all those you have lost, and go into your room and spend some time looking at them. Bring some paper, and write down your thoughts. Start a binder, and get a page for each person you've lost, and put their picture at the front, and every time you think of something about them, right it down. Keep it on your bookcase.
Then go kick life's ass again.
